            TSMC 2003 Third Quarter Sales Revenue Hit New Record High


Hsinchu, Taiwan, October 28, 2003 - Taiwan Semiconductor Manufacturing Company
Ltd. (TAIEX: 2330, NYSE: TSM) ("TSMC") today announced its financial results for
the third quarter of 2003. Net sales for its third quarter reached a new record
high of NT$54,877 million, while net income totaled NT$15,169 million. Earnings
per share were NT$0.75 based on the current 20,226,848 thousand weighted average
outstanding shares.

For the nine months ended September 30, 2003, the Company's net sales were
NT$144,125 million, while net income reached NT$31,256 million. Earnings per
share for the nine months ended September 30, 2003 were NT$1.54.

On a sequential basis, the Company's 2003 third quarter net sales grew 9.9
percent, net income increased 29.3 percent, and earnings per share grew 29.5
percent.

Compared to the same period for last year, TSMC 2003 third quarter net sales
grew 37.8 percent. Net income and earnings per share grew substantially by 380.0
percent and 395.4 percent, respectively, over 2002 third quarter.

Ms. Lora Ho, TSMC spokesperson and vice president, noted that, "Due to growth in
customer demand, TSMC's 2003 third quarter wafer shipments continued to
increase, reaching 992,000 eight-inch-equivalent wafers, for a 12 percent
increase over last quarter. On a sequential basis, average selling price (ASP)
remained flat. However, the exchange rate between US dollars and NT dollars was
weaker in 2003 third quarter. As a result, total net sales for the third quarter
of 2003 grew 9.9 percent sequentially."

Ms. Ho added that, "Revenues from TSMC's advanced process technologies,
including 0.18-micron and below process technologies accounted for 66 percent of
total wafer sales in the third quarter of 2003. The 0.13-micron process
technology alone accounted for 19 percent of our total sales. In addition, the
average utilization rate for the third quarter of 2003 increased to 98 percent
as compared to 88 percent for the second quarter of 2003. As a result, gross
margin for the third quarter of 2003 improved to 39.1 percent versus 36.8
percent in the previous quarter."
